The historically informed performance, period performance, or authentic performance movement is an approach by musicians and scholars to research and perform works of
classical music in ways similar to how they may have been performed when they were originally written. The movement had its beginnings in the performance of
Medieval,
Renaissance, and
Baroque music, but subsequently came to incorporate the
Classical and even
Romantic eras as well. The two methods adopted by historically informed performance artists have been to use period instruments and to utilise treatises and other written evidence to gain insight into performance practice, i.e. stylistic and technical considerations based on how the works may have been played in the period in which they were written.
